Application filed :2, 1916. Eerie; Jifio.

To all '20 7mm it may concern:

Be it known that I, EDWIN Buses, a citizen or" the United States, residing at Chicago, .Illinois, have invented acertain new and useful Improvement in Brake-Beams, of which the following is a full, clear, and exact description, such as Will enable others skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, forming part of this specification, in Whichigure 1 is a top plan.- view of my improved brake beam. F 2 is a side elevational view showing the strut thereof. Fi m 3 is a sectional View through the strut on line 3-3 of Fig. 2.

This invention relates to a new and usetui improvement in brake beams and particularly the strut thereof.

Heretofore it has been the practice to employ a Wedge key to tighten the strut on the compression-member and it is one of. the objects of my invention to utilize a filler block which .Will dispense with the wedge key.

It is also an object of my invention to increase the lengthcf the brake lever slot Will hereinafter appear.

In the drawings '1 indicates the U-shaped compression member of a brake beam and 2 isthe filler block seated therein and extending outwardly theitebeyond, said filler block having inclined faces 3, the forward extension 4 having an elongated opening,

5 is the strut which is bent into shape to embrace the compression member 1, said strut having inclined faces 6 in advance of the compression member for engagement With the inclined faces 3 of the filler block. A bolt 7 passes through the strut and the elongated opening in the forward extension 4 of the filler block and When this bolt is tightened the members of the strut are brought together, the filler block is forced into the compression member and all of the parts including the strut, tie compression member, and the filler block are clamped tightly in position b r the bolt 7. It will be noted that the filler block is free from the legs of the coinpren elongated openim thereof, througi which the bolt '2' passes, permits a limited freedom of movement of the filler iQl-OClK-Wlllflil enables it to find its seat in the final clamping adjustment of the parts. The toiwvard free ends of the strut also contain a filler block 8, said ends being formed with elongated openings 9 for the passage of the tension member 10, It has heretofore been the practice to rivet the free ends of the strut inside the tension member, but I propos in my present construction, to extend the free ends of the tension member, and the tiller block, outwardly beyond. the tension member so as to enable the location of a rivet in such mitW-ard extension In this WayI ainienabled to obtain a long lever slot. The filler block 8 may nave an upward eictension S for a third suspending link, or it may have outwardiy and downmembers provided with openings for the passage of the tension member, a filler block between said members, and securing means located outside of the tension member openings for holding filler block.

In t stimony whereof I hereunto aiiix my signature in the presence of two Witnesses, this 24th day of February, 1916.
